Mictlantecuhtli was a god of the dead and the king of Mictlan (Chicunauhmictlan), the lowest and northernmost section of the underworld. He was one of the principal gods of the Aztecs and was the most prominent of several gods and goddesses of death and the underworld. The worship of Mictlantecuhtli sometimes involved ritual cannibalism, with human flesh being consumed in and around the temple.
The Olmec culture was the first great Mesoamerican civilization, developing along Mexico's gulf coast from about 1200-400 B.C. before going into a mysterious decline. The Olmec were very talented artists & sculptors who are today best remembered for their monumental stonework and cave paintings.
